COMPRESSION READINGS...

I have a Ford 1982 E-Van straight six. I had a real scare the other day and thought that I had blown a head gasket... After getting the engine to purr like a kitty. But, when I checked the engine compression readings and they were; CYL 1, 135; CYL 2, 132; CYL 3, 129; CYL 4, 137; CYL 5, 140, and CYL 6, 138. Are these good readings for this type of engine? I was thinking to also check the head bolts and make sure that they are tightened to spec.

The scare was this... While I was driving a short distance, the engine just threw off the water pump/alternator/crank pully belt. The water came out of the coolant reservoir and leaked at the radiator. However a close inspection of the radiator shows it might be a loose belt---haven't had a chance to check it out yet. I have a hunch that the water pump pully may be the cuprit for throwing the belt, but I haven't been able to prove that yet.

Thanks for any advice and help you can be. :D
